I assume they are in the typical "blue/green/aqua" color. Millions of those have been produced over the years. They an quite common, and have no significant value. Other colors, purple, jade and others can be more valuable. Additional information about this insulator can be found at http://www.insulators.info/general/profiles/106hemi.htm The "MAY 2 1893" date refers to the "drip points" (bumps) on the bottom of the insulator. This is the patent for those: http://reference.insulators.info/patents/detail/?patent=496652&type=U Bill Meier

The 1900 is worth about $17.00. The 1893 is worth a whole lot, somewhere around 1,800 dollars but the 1900 isnt worth as much.
